Ubuntu System get Unbootable after User Install Meltdown and Spectre Patches

Code Bytes: Some Ubuntu Xenial 16.04 users have found that after installing the Meltdown patch, they are unable to boot their systems and are forced to roll back to an earlier Linux kernel image. The update led to a flurry of activity on the Ubuntu forums and other Linux resources online, with users complaining that moving to kernel image 4.4.0-108 was causing issues.

Canonical has addressed the problem in an Ubuntu security notice, affected users are advised to switch to the last working kernel version via GRUB. After that, they can remove the buggy kernel update and install new kernel version 4.4.0-109-generic via system update which is working fine according to Canonical.

However, it’s known that the new kernel update is not fixing problems for all users. So, the users still affected can stick to 4.4.0-104-generic.

The news about Ubuntu system going unbootable comes just days after we heard about unbootable AMD systems due to Microsoft’s Meltdown fixes for Windows 10 devices. Microsoft had to temporarily halt the roll-out of Meltdown and Spectre patches.
